open the floodgates
Meaning
To allow something to start happening in large amounts, often suddenly and hard to control.
Origin
From literal floodgates used on dams, canals, and levees to control water flow; opening them releases a large surge of water. Figuratively, it came to mean unleashing a sudden, overwhelming flow of events, emotions, or actions.
Notes
Figurative and a bit dramatic. Often implies an overwhelming surge and sometimes a risk of encouraging more (e.g., complaints/lawsuits), but can also describe emotions suddenly pouring out.
